Written Requests Send your extension request in writing (not by telephone) to the district office in your area, with the heading "Attn: Extensions"

For proof you mailed your request, we recommend you get a USPS certificate of mailing

Note: For Manufacturing real and personal property, you must also:

Identify each manufacturing personal property account requesting a filing extension by either its 9 digit account number (ex: 000099999) or its full state identification number (ex: 76 13 251 P 000099999)

If you are filing extension requests for multiple owners, you must submit a separate request for each owner identifying every account requesting an extension

Extension Filing Deadline

If you are granted an extension, state law allows one filing extension to April 1, 2014. DOR must receive your extension request on or before March 3, 2014. For more information, see "Request an Extension" above.

Late Filing Penalty

If you do not file your M-Form or file it late, you will receive a non-filing penalty and lose the right to appeal your assessment. See Late filing fee.
